Abstract Current induced spin-orbit torques driven by the conventional spin Hall effect are widely used to manipulate magnetization. This approach, however, is nondeterministic and inefficient for switching of magnets with perpendicular magnetic anisotropy that demanded high-density storage memory devices. Here, we demonstrate this limitation can be overcome exploiting a in noncollinear antiferromagnets, such as Mn 3 Sn. The group symmetry Sn allows generation out-of-plane current carrying...
Abstract Due to its inherent superior perpendicular magnetocrystalline anisotropy, the FePt in L 1 0 phase enables magnetic storage and memory devices with ultrahigh capacity. However, reversing state, therefore encoding information, has proven be extremely difficult. Here, it is demonstrated that an electric current can exert a large spin torque on magnet, ultimately leading reversible magnetization switching. The monotonically increases increasing thickness, exhibiting bulk characteristic....

The effects of rare earth (RE) addition on the corrosion behavior micro-alloyed steels in 3.5 wt.% NaCl solution were investigated elaborately through electrochemical tests and material characterization analyses. Results showed that rate decreased after RE elements. elements did not alter pitting nucleation mechanism, while sensitivity propagation was reduced by decreasing density depth. In long-term corrosion, preferential precipitation products promoted formation protective rust layers...
